Severe dual fungal infection after bispecific antibody therapy: A case of invasive aspergillosis and mucormycosis in immunocompromised patient.

Bispecific antibody is a new treatment for hematological disease, especially for lymphoma, myeloma and acute lymphoblastic leukemia. This class of treatment presents the same kind of side effect as CAR-T cell which are immune-mediated. Nevertheless, infectious complication remains a major concerns with related mortality.

[Retrospective study on smoking in lung cancer at the University Hospital of Liège].

This retrospective study including 93 patients who presented a new diagnosis of lung cancer at the University Hospital of Liege between January 2023 and April 2023 analyzed the prevalence of smoking cessation following the diagnosis announcement. It was also investigated whether certain factors influenced this rate (stage, histology, type of treatment received, tobacco monitoring,…) and whether the impact of this smoking cessation influenced the progression of the disease and the response to oncological treatments. The results show that 34.

The impact of Charcot-Leyden Crystal protein on mesothelioma chemotherapy: targeting eosinophils for enhanced chemosensitivity.

Background: In mesothelioma (MPM), clinical evidence indicates that the absolute eosinophil count negatively correlates with overall survival and response to standard chemotherapy. Since eosinophils poorly infiltrate MPM tumours, we hypothesised that endocrine rather than paracrine pathways mediate the therapeutic response. We thus studied the effect of eosinophil-associated factors on response to chemotherapy in mesothelioma.

Identification of CT radiomic features robust to acquisition and segmentation variations for improved prediction of radiotherapy-treated lung cancer patient recurrence.

The primary objective of the present study was to identify a subset of radiomic features extracted from primary tumor imaged by computed tomography of early-stage non-small cell lung cancer patients, which remain unaffected by variations in segmentation quality and in computed tomography image acquisition protocol. The robustness of these features to segmentation variations was assessed by analyzing the correlation of feature values extracted from lesion volumes delineated by two annotators. The robustness to variations in acquisition protocol was evaluated by examining the correlation of features extracted from high-dose and low-dose computed tomography scans, both of which were acquired for each patient as part of the stereotactic body radiotherapy planning process.

Predictive clinical and dosimetric parameters for risk of relapse in early-stage non-small cell lung cancer treated by SBRT: A large single institution experience.

Purpose: To evaluate the impact of dosimetric parameters on efficacy of stereotactic body radiation therapy (SBRT) in early-stage non-small cell lung cancer (ES-NSCLC), using Hypofractionated Treatment Effects in the Clinic (HyTEC) reporting standards.

Methods: From April 2010 to December 2020, 497 patients who received SBRT for ES-NSCLC at the University Hospital of Liège were retrospectively enrolled. A total dose of 40 to 60 Gy in 3-5 fractions (72-180 Gy biologically effective dose with an α/β ratio of 10 (BED)) was prescribed to the 80 % isodose line of the PTV.

[Probe based confocal laser endomicroscopy in thoracic endoscopy].

Introduction: Probe based confocal laser endomicroscopy (pCLE) is a new endoscopic imaging technology. It uses mini probes which can be introduced through the working channels of endoscopes. Whenever applied on the tissue of interest, they allow imaging of tissue at a cellular level.

[Clinically amyopathic dermatomyositis : a rare entity associated with acute and severe interstitial lung disease].

Dermatomyositis is a rare disease of unknown etiology characterized by a severe inflammatory myopathy associated with a cutaneous syndrome. Dermatomyositis is associated with multisystemic disorders mostly represented by cardiac, pulmonary and articular involvements, which are particularly associated with a bad prognosis. We report a case of a 50-year-old patient suffering from dermatomyositis associated with an interstitial lung disease with a particularly fast and pejorative clinical evolution.

Radiomics and Delta-Radiomics Signatures to Predict Response and Survival in Patients with Non-Small-Cell Lung Cancer Treated with Immune Checkpoint Inhibitors.

The aim of our study was to determine the potential role of CT-based radiomics in predicting treatment response and survival in patients with advanced NSCLC treated with immune checkpoint inhibitors. We retrospectively included 188 patients with NSCLC treated with PD-1/PD-L1 inhibitors from two independent centers. Radiomics analysis was performed on pre-treatment contrast-enhanced CT.

Excess of blood eosinophils prior to therapy correlates with worse prognosis in mesothelioma.

Background: Only a fraction of patients with malignant pleural mesothelioma (MPM) will respond to chemo- or immunotherapy. For the majority, the condition will irremediably relapse after 13 to 18 months. In this study, we hypothesized that patients' outcome could be correlated to their immune cell profile.

[Life-threatening flare of an underlying «paraneoplastic» dermatomyositis in a patient with lung adenocarcinoma treated with anti-PD-1 pembrolizuma].

Dermatomyositis is an autoimmune disease mainly characterized by muscle and skin involvement. Its association with cancer is known but the term «paraneoplastic» remains debated. We report here the case of a 71-year-old woman with a new diagnosis of dermatomyositis with, at the same time, the discovery of a lung adenocarcinoma.

HDAC Inhibition with Valproate Improves Direct Cytotoxicity of Monocytes against Mesothelioma Tumor Cells.

The composition of the tumor microenvironment (TME) mediates the outcome of chemo- and immunotherapies in malignant pleural mesothelioma (MPM). Tumor-associated macrophages (TAMs) and monocyte myeloid-derived immunosuppressive cells (M-MDSCs) constitute a major fraction of the TME. As central cells of the innate immune system, monocytes exert well-characterized functions of phagocytosis, cytokine production, and antibody-dependent cell-mediated cytotoxicity (ADCC).

Eosinophilic Pleural Effusion Induced by Paliperidone Palmitate: Case Report and Literature Review.

Background: Eosinophilic pleural effusions are defined by an eosinophil count ≥ 10% in pleural fluid and represent approximately 10% of exudative pleural effusions. They are associated with a large spectrum of etiologies, both benign and malignant. Drug-induced eosinophilic pleural effusions remain rarely described.

Oncological patients' reactions to COVID-19 pandemic: A single institution prospective study.

Background: The spread of the COVID-19 pandemic has led to a rapid reorganization in all human and hospital activities, with impact on cancer patients.

Aim: An analysis of cancer patients fears, and awareness of COVID-19 has been done in this study.

Methods And Results: We analyzed cancer patients' reactions to the pandemic and their perception of oncological care reorganization, through a 12-item survey, proposed at the peak of pandemic and 3 months later.

White Blood Cells in Patients Treated with Programmed Cell Death-1 Inhibitors for Non-small Cell Lung Cancer.

Purpose: To investigate whether eosinophils and other white blood cell subtypes could be used as response and prognostic markers to anti-Programmed cell Death-1 or anti-PD-Ligand-1 treatments in non-small cell lung cancer patients.

Methods: We retrospectively analyzed data from the NSCLC patients consecutively treated at our hospital with a PD-1/PD-L1 inhibitor in monotherapy for advanced disease. A total of 191 patients were evaluated at three time-points to investigate any relation between tumor response and WBC counts.

[Targeted therapies for non-small cell lung cancer : state of the art in 2021].

The majority of non-small cell lung cancers are diagnosed as advanced disease. Subsets of adenocarcinomas and of squamous cell carcinomas in nonsmokers present a molecular aberration leading to tumour survival. Epidermal Growth Factor Receptor (EGFR), Anaplastic Lymphoma Kinase (ALK) and Repressor Of Silencing1 (ROS1) have been identified and targeted with good efficacy for fifteen years.

[Small cell lung cancer : update of therapy].

Small cell lung cancer is a malignant tumour with a poor prognosis. Standard treatment of metastatic stages has been a platinum doublet since 1980, but the addition of immunotherapy has improved prognosis. For locally advanced stages, the combination of radio-chemotherapy remains the treatment of choice, with no evidence at present of the value of immunotherapy in consolidation, and for localized stages, surgery is the first-line therapy.

[Non small cell lung carcinoma in never-smokers at the Liege University Hospital : a retrospective cohort study, 2017-2018].

Lung cancer is the third most common cancer in Belgium in 2017 and remains the leading cause of cancer death worldwide. There is no longer any doubt that the main cause of lung cancer is smoking. However, the prevalence of lung cancer in never-smokers has been increasing overtime.

[Pre-cancerous lung lesions and lung cancer screening].

Lung cancer remains the deadliest cancer. It is the result of genetic aberrations in the cells of the respiratory tract exposed to carcinogenic agents, responsible for their anarchic multiplication. It is necessary to study these abnormalities in order to better understand the early stages and the mechanisms of evolution, thereby to establish new screening, monitoring and treatment strategies.

[Managing of dyspnea in oncology].

The perception of ventilatory effort is common in oncology, especially but not exclusively in the advanced stages of neoplastic disease. Dyspnea is a symptom whose discomfort and anguish it generates in the patient and his/ her entourage require constant management throughout the illness. The first step is to identify and optimize the treatment of comorbidities associated with tumour disease.

[Cystic lung diseases].

Cystic lung diseases present uncommonly and have an undetermined incidence. Cysts result from a broad spectrum of causative mechanisms and diseases leading to variable clinical presentations. The pathogenic mechanisms that can lead to lung cyst formation include infection, neoplastic, systemic, traumatic, genetic and congenital processes.

[Empyema and subacute invasive aspergillosis following drowning].

Empyema and subacute invasive aspergillosis are rare pathologies that should not be overlooked because of the need for early treatment and a different management of bacterial infections which are more frequent. We report the case of a 75-year-old man with subacute invasive aspergillosis and an empyema following drowning and cardiopulmonary arrest.

Could KL-6 levels in COVID-19 help to predict lung disease?

Background: Coronavirus disease COVID-19 has become a public health emergency of international concern. Together with the quest for an effective treatment, the question of the post-infectious evolution of affected patients in healing process remains uncertain. Krebs von den Lungen 6 (KL-6) is a high molecular weight mucin-like glycoprotein produced by type II pneumocytes and bronchial epithelial cells.

Asthma and COPD Are Not Risk Factors for ICU Stay and Death in Case of SARS-CoV2 Infection.

Background: Asthmatics and patients with chronic obstructive pulmonary disease (COPD) have more severe outcomes with viral infections than people without obstructive disease.

Objective: To evaluate if obstructive diseases are risk factors for intensive care unit (ICU) stay and death due to coronavirus disease 2019 (COVID19).

Methods: We collected data from the electronic medical record from 596 adult patients hospitalized in University Hospital of Liege between March 18 and April 17, 2020, for severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection.
